Bed-wetting or Enuresis can defined as a complete or near-complete micturition in the bed during sleep. The most common form of bed-wetting is monosymptomaticnocturnal enuresis (MNE) meaning that there are no daytime symptoms pointing to bladder dysfunction. Thus, the child has no pronounced urgency, no very frequent nor infrequent voiding and, most important, no daytime incontinence.
